I really like these A-11 aircraft panel clocks. All of the makers of them during the war really built them to last. Could you post a photo of the data plate on the back of its case?

Actually they only had one mainspring in the Waltham A-11 as well as the Elgin with mostly the 562 grade movement. The only A-11 I know of with 2 mainspring barrels is a Wittnauer.
I've overhauled all the US ones of that era and the Wittnauer is my favorite due to its rugged movement. The Lemania's that are in so many planes are my least favorite as the escape wheel pivots are way to fragile for the application.
